Monomeric Proteins

Before diving into what is Monomer of protein? We must first understand the history of monomers and the role they play in chemical composition. Well, all chemicals form by a high percentage of small monomeric structures. Monomers have also played a crucial role in the rise of the plastic age. Since we had an abundance of diverse chemical supplies at low costs, it fueled researchers to study monomers. These studies led to the development of hybrid materials through a technique in which different monomer structures join together via polarization and copolymerization. Also, During industrialization, the rise of petrochemical products was a direct result of the diversification of structures that further led to the development of organic chemistry. Now, let us dive into what is Monomer of protein bonds and protein monomer name?

The Monomers of Protein Bonds

So what is Monomer of protein bonds? All living organisms have cells, and these cells have several large molecules such as nucleic acids, polysaccharides, and proteins. These large molecules have even smaller structures or units by combining them in large quantities. We refer to these large numbers of small structures as monomers. The linking makes polymers or macromolecules of several monomers. This Monomer linking up to form the chain of molecules is only possible due to the presence of carbon and its valency properties. We can form a variety of chains of monomers, such as sugar monomers, nucleotides, and amino acids. 

All living cells essentially require nucleic acids and protein in the life process. Did you know that proteins are composed of monomeric building blocks called amino acids? So we can say that proteins are made of monomers called amino acids. The process of polymerization forms them. These building blocks monomers of proteins are further crucial in the life processes. We are now able to produce protein-like polymers by controlling the conditions and performing polymerization of amino acids. By repeating this process, we produce sugars and nucleotides, which are comparatively easier to prepare than amino acids. Different biomolecules took form by utilizing this similar process. All these development aids in the field of bioengineering to develop a variety of biopolymers.


Elements such as Oxygen, nitrogen, hydrogen, and carbon bond covalently to form proteins, and sulfur can also be present in some cases. Before getting into the structure of proteins, we must first understand the structure of their atoms. Globular structures are only possible due to the reverse direction of polypeptide chains which is a direct result of about a third of its residues in loops. We recognize these loops as a type of ordered secondary structures. These loops have classification according to the type of structure they connect and the number of residues. 

Moreover, we know that proteins are made of monomers called amino acids. There are up to twenty amino acids or building blocks of protein that vary in atoms connected and the length of their carbon chain. So we can call protein monomer names as amino acids. Every amino acid consists of hydrogen, amine, R group, and the carboxyl group. The bonds formed covalently between various amino acids during the formation of proteins are known as peptide bonds. We use proteins to perform various crucial functions in our body, and most of these proteins are structural proteins.

The structure of the protein contains mainly 4 monomer protein structures. We call them a quaternary structure, tertiary structure, secondary structure, and primary structure. In the primary structure, proteins coil into pleated sheets and helices. Also, the amino acids sequence determines the primary structure, whereas hydrogen bonds joining amino acids determine the secondary structure of proteins. In the secondary structure, a single protein has a helix or coiled shape structure with hydrogen bonds. It is only possible to break these hydrogen bonds by changing the surroundings such as induce high temperatures or increase acidic property. In the tertiary structure of the protein, the sulphur atoms in amino acids bond tightly via peptide bonds. Lastly, in quaternary structures, individual units are connected spatially.

Building Blocks Monomers of Proteins

Let us answer the question: what are the monomers of proteins called? The building blocks monomers of proteins are known as amino acids. In other words, the protein monomer name is amino acids. There are twenty types of amino acids and proteins are made of a combination of these amino acids. Furthermore, there are a few other types of building blocks of proteins depending upon the varying size of molecules. Generally, we categorize them as essential and non-essential building blocks of proteins depending upon their requirement. Also, we can make up to ninety thousand combinations or arrangements of proteins using these amino acids. 

Additionally, nucleotides have the building blocks of nucleic acid chains.

FAQ (Frequently Asked Questions)

1. What are the Functions of Protein in the Human Body?

Proteins have several vital functions in the human body, including growth and maintenance. We mainly use proteins by breaking them down to repair tissue damage in the body. Sometimes our bodies require more breaking down of proteins such as during an illness or pregnancy. These proteins aid in a variety of biochemical reactions that take place in the body. Also, they can act as messengers to improve communication between organs, cells, and tissues. The fact that we have some stiff and rigid muscles are solely due to protein fibres maintaining the structure. In addition to that, proteins aid in providing energy, storing nutrients, immunity, maintaining pH and balancing fluids.  

2. How are Protein Monomers Categorized?

Proteins are made of monomers called amino acids, and we can categorize proteins based on requirements into two different categories essential and non-essential. The non-essential protein monomers can be further classified based on the water into hydrophilic and hydrophobic. We have around nine necessary protein monomers or amino acids from which adults require only eight of them. The essential protein monomer example is isoleucine, lysine, leucine, valine, threonine, tryptophan, methionine, and phenylalanine.

In contrast, the ninth(histidine) is for infants. The human body does not require the rest. We call them glutamine, cysteine, arginine, glycine, tyrosine, ornithine, asparagine, aspartate, alanine, serine and proline. The body mainly generates essential amino acids.
